Definitions
- the invention is concerned with new [bis(hydroxymethyl)-methyl]-isoquinoline derivatives as well as with a process for preparing them and pharmaceutical compositions, particularly with neuroleptic and anticonvulsive activity, containing these compounds.
- the problem underlying to the invention is to create novel [bis(hydroxymethyl)-methyl]-isoquinoline derivatives having valuable pharmacological effects and further serving as intermediates for preparing other isoquinoline derivatives having valuable pharmacological properties, a process for preparing them and pharmaceutical compositions containing them.
- the subject-matter of the invention are [bis(hydroxymethyl)-methyl]-isoquinoline derivatives of the formula (I) wherein
- the subject-matter of the invention is also a process for preparing the compounds according to the invention which is characterized in reacting a 1-methyl-3,4-dihydroisoquinoline of the formula (II) or a 1-((3-hydroxyethyl)-3,4-dihydroisoquinoline of the formula (III) wherein R 1 and R 2 are as defined above, with formaldehyde, the hydrate or trimeric derivative thereof, then, if desired, hydrogenating a bis[(hydroxymethyl)-methyl]-3,4-dihydroisoquinoline derivative of the formula (IV) obtained, wherein R 1 and R 2 are as defined above, and/or, if desired a compound of the generic formula I obtained, wherein R 1 and R 2 are a C 1-6 alkoxy group, is converted by dealkylation into a compound of the generic formula I containing as R 1 and R 2 a hydroxyl group, and/or, if desired, a compound of the generic formula I obtained, wherein R 1 and R 2
- the 1-methyl- and 1-( ⁇ -hydroxyethyl)-isoquinoline derivatives of the formulae (II) and (III) used as starting materials, in which R 1 and R 2 are as defined above, are known in the art, and can for example be prepared from homoveratryl amine or the corresponding ⁇ -phenylethyl amine derivative by acetylation and a subsequent ring closure conventionally used for preparing isoquinoline compounds, e.g. Bischier-Napieralski synthesis.
- the hydrate or trimeric derivative thereof i.e. paraformaldehyde or trioxane, which are commercially available materials.
- the reaction is preferably carried out in alkaline medium, most preferably in the presence of an alkali metal alcoholate or alkali metal hydroxide.
- an alkali metal alcoholate for example sodium methylate or sodium ethylate
- an alkali metal hydroxide for example sodium or potassium hydroxide is employed.
- the starting compounds of the formulae (II) and (III) are preferably reacted with formaldehyde and derivatives thereof in an inert organic solvent, such as an alcohol having from 1 to 6 carbon atoms, e.g. methanol; or in an aromatic hydrocabron, e.g. benzene.
- an inert organic solvent such as an alcohol having from 1 to 6 carbon atoms, e.g. methanol; or in an aromatic hydrocabron, e.g. benzene.
- Formaldehyde and derivatives thereof may be used in an equimolar amount related to the starting compounds, or in a slight excess.
- a small amount of a 1-((3-hydroxyethyl)-isoquinoline derivative can also be isolated as a by-product, which can easily be separated from the main product, e.g. by recrystallization from ether.
- the reaction temperature may be varied within wide limits, but preferably it is between room temperature and the reflux temperature. Most preferably the reaction is carried out around room temperature.
- the reaction time is a function of temperature and other reaction conditions, e.g. the reactants and medium employed, and generally amounts to several hours.
- Hydrogenation can be performed with any conventional hydrogenating agent, such as a complex metal hydride or with hydrogen in the presence of a catalyst.
- a complex metal hydride for example sodium-tetrahydroborate (III) or lithium-aluminium hydride is employed.
- Catalytic hydrogenation is carried out under normal conditions, preferably in ethanol, in the presence of a catalyst conventionally used for hydrogenation, e.g. palladium-on-charcoal or platinum oxide.
- Salt formation can be carried out in an inert organic solvent, for example in a C 1 - e aliphatic alcohol, by dissolving the compound of the formula (I) in the solvent and the selected acid or by adding a solution thereof formed with the same solvent to the first solution until it becomes slightly acidic (pH 5 to 6). Thereafter the acid addition salt separates out and may be removed from the reaction mixture e.g. by filtration.
- an inert organic solvent for example in a C 1 - e aliphatic alcohol
- the compounds of the formula (I) or the salts thereof, if desired, can be subjected to further purification, e.g. recrystallization.
- the solvents used for recrystallization are selected depending on the solubility and crystallization properties of the compound to be crystallized.
- the substituents R 1 and/or R 2 can easily be converted into other substituents within the definition of R 1 and R 2.
- compounds of the formula (I) in which R 1 and/or R 2 is hydroxyl can be converted into the corresponding compounds of the formula (I), in which R 1 and/or R 2 represent an alkoxy group having from 1 to 6 carbon atoms, by methods known in the art.
- the 6,7-dimethoxy compounds are most expediently prepared by methylation of the corresponding 6,7-dihydroxy compounds with diazomethane or dimethyl sulfate.
- the higher ethers can for example be prepared by the Wiliamson synthesis, using alkyl iodides.
- R 1 and/or R 2 represent an alkoxy group having from 1 to 6 carbon atoms
- the corresponding compounds containing hydroxyl as R 1 and/or R 2 can be obtained by known reactions, e.g. heating with hydrogen bromide or hydrogen iodide or by means of anhydrous aluminium chloride.
- compositions which contain one or more compound(s) according to the invention as [an] active ingredient(s), suitably together with one or more pharmaceutical carrier(s) and/or excipient(s), are provided for.
- the compounds according to the invention are pharmaceutically active, e.g. show neuroleptic and anticonvulsive activity.
- the compounds according to the invention are further useful intermediates in the preparation of other pharmaceutically active isoquinoline derivatives.
- they can be converted into various pharmaceutically active N-substituted [bis(hydroxymethyl)-methyl]-isoquinoline derivatives having for example immunsuppressive, anticonvulsive, analgesic or antipyretic activity, by conventional techniques of N-substitution. Further details of this process are disclosed in the European Patent Application 84 112 855.6, published under the number EP ⁇ A ⁇ 142 740. Further valuable compounds are obtained if in the compounds of the formula (I) one or both hydroxyls of the bis(hydroxymethyl)-methylene group are replaced by other substituents, e.g. acyl groups.
- Example 1 The procedure described in Example 1 is followed except that instead of 1-methyl-6,7-dimethoxy-3,4-dihydroisoquinoline an equivalent amount of 1-methyl-6,7-diethoxy-3,4-dihydroisoquinoline is used as a starting material. Evaporation of the reaction mixture under reduced pressure and recrystallization of the crude product obtained from benzene yields the aimed compound.
- Example 2 Following the procedure described in Example 1 but replacing sodium ethylate by an equivalent amount of sodium methylate at a catalyst, the aimed compound is obtained, which has the same melting point as given in Example 1:
- Example 2 Following the procedure described in Example 1 but replacing sodium ethylate by an equivalent amount of sodium hydroxide as a catalyst, the aimed compound is obtained which has the same melting point as the product obtained in Example 1.
- Example 1 0.1 mole of 1-[bis(hydroxymethyl)-methyl]-6,7-dimethoxy-3,4-dihydroisoquinoline obtained in Example 1 is dissolved in 180 ml of absolute ethanol, and then a 1.5-fold excess of dry hydrogen chloride gas dissolved in absolute ethanol is added to the solution. After recrystallization from a mixture of methanol and ether the obtained 1-[bis(hydroxymethyl)-methyl]-6,7-dimethoxy-3,4-dihydroisoquinoline hydrochloride melts at 181 to 184°C.
- the 6,7-diethoxy analogue of the above compound can be prepared in an analogous manner, starting from 1-[bis(hydroxymethyl)-methyl]-6,7-diethoxy-3,4-dihydroisoquinoline; melting point: 127 to 128°C (benzene).
- the product obtained does not give any melting point depression when admixed with the product prepared according to Example 10.
- Reaction time 4 to 6 hours.
- the product obtained does not give any melting point depression when admixed with the products obtained in Examples 10 and 13.
- the product obtained has analgesic and antipyretic activity.
